Any issues with the actual running of the WRF.

WRF 3.8.1 ideal "Chemistry routines ... land use maps ..."

Hi there:

Brand new WRF user here. I am wondering if anyone had this problem before.

Downloaded and compiled WRF + WRF_Chem 3.8.1 em_b_waves. For a test I compiled serial / gcc / gfortran.

ideal.exe went through without complaints. When I started wrf.exe I go the following error:

Code: Select all
-------------- FATAL CALLED ---------------
FATAL CALLED FROM FILE:  <stdin>  LINE:     424
 ERROR: CHEM_INIT: Chemistry routines require USGS or MODIS_NOAH land use maps. Need to change land use option.
-------------------------------------------


Looking at namelist.input, I have the following lines under &physics, right out of the box:

Code: Select all
 sf_sfclay_physics                   = 0,     0,     0,
 sf_surface_physics                  = 0,     0,     0,


if I change sf_surface_physics to 2 (NOAH), WRF went a bit further (i.e., allocated memory) and then reported another error (which I think makes sense because I did not really supply any land use information):

Code: Select all
-------------- FATAL CALLED ---------------
FATAL CALLED FROM FILE:  <stdin>  LINE:     752
Mismatch between namelist and global attribute SF_SURFACE_PHYSICS
-------------------------------------------


I though the WRF ideal cases would run out of the box. If I was supposed to introduce customization, I would like to know what these would be.

Again, thanks in advance for your assistance and ideas.

Gerry.
